Destination Rides? Women’s-Specific Trail Work Days? Bike Mechanic Clinics? YES, PLEASE!

In addition to hosting local rides in Marin on classic trails that include Tamarancho, Solstice, and China Camp, we also host destination weekend rides to awesome trails in Santa Cruz, Tahoe, and Mendocino. We’re also planning on hosting women’s specific trail work days, bike mechanic clinics, women’s mountain bike skills clinics, and of course — social events. Our goal is to help every rider feel confident and up her game, in a supportive community. Your membership gets you access to all these awesome events and helps support the Access4Bikes mission of maintaining and building trails. Join us!

MOUNTAIN BIKERS ARE THE SECOND LARGEST USER GROUP IN MARIN’S PUBLIC LANDS.

Surveys conducted in 2011-2012 by MMWD and MCOSD put the number anywhere from 23-30%. In the last seven years, that percentage has steadily risen.

We are happy and willing to lead the way in trail stewardship and environmental protection with our growing demographic and enthusiastic volunteer corps.
